Problems solved by technology

For instance, current market conditions and operating costs may prevent the economic extraction of material below a predetermined depth in the mine pit.
For example, referring to FIG. 1, ore mined from block A could be dispatched to a smelter because of its high mineral content, while material from block C would be sent to the dump because current operating costs and market conditions would not justify its exploitation.
Because of the human factor involved in this dispatching process, errors are easily made and difficult to recognize and correct.
Surface markers, such as stakes and tapes laid out on the surface between mining blocks, can become dislodged by equipment, wind and dirt slides; in addition, machine operators can

Embodiment Construction

For the purposes of this disclosure, it is understood that every reference to an operator is intended to apply as well to an onboard automated control system. Surface mines utilize a variety of work machines for excavating and transporting ore, grading and stabilizing roadways and slopes in the mine pit, and providing all support functions necessary to the operation of a mine. Most work machines, such as excavators, shovels, backhoes and the like, are human-operated, mobile pieces of equipment constantly being moved around the surface of the mine. Skilled operators ensure that each mining machine is positioned in the right place and optimally oriented to perform its intended function. For example, an excavator operator will ensure that the undercarriage of the machine is sufficiently close to the minable seam and that its boom is oriented so as to permit the bucket of the machine to reach and extract a full load of ore.

In order to improve safety and efficiency, much effort is curren...

Abstract

An autonomous dispatch system links positioning-system units mounted on mining and haulage equipment to a computerized mine development plan for ascertaining the origin of mined material and directing its disposition according to a predetermined downstream-processing plan. A destination signal is automatically communicated to the haulage vehicle, which is then autonomously guided to the correct destination and tracked until the load is released after arrival. If the haulage vehicle is manually operated, the destination signal and the vehicle's progress toward it are preferably also displayed on a monitor for the operator's information and use. The system may further include hardware for blocking the release of a load from the haulage vehicle until and unless the vehicle has reached the prescribed destination.

Description

1. Field of the InventionThis invention is related in general to mining systems and, in particular, to a novel approach for dispatching mine trucks from the mining site to the appropriate destination according to a predetermined mine development plan.2. Description of the Related ArtSurface mine development plans outline a proposed mining sequence according to the quality of the ore and mining conditions present in various parts of the mining property. As one skilled in the art would readily understand, drill-core samples are routinely taken from the mine property and assayed to assess the mineral content and rock characteristics of various regions within the mine boundary. Based on these data, three-dimensional maps of the mine are developed showing various properties of interest, such as the average mineral content, as a function of depth and location within the mine property. For example, referring to the drawings, wherein like parts are designated throughout with like numerals a...
